Abstract: The Perceptual Ontology,whose naissance was very important in the history of western philosophy in the early 1800s,was firstly advocated by Feuerbach.Marx took a full understanding of it and later evolved it into the practical Ontology,which shouldered the task of thoroughly subverting the traditional philosophy,especially the modern philosophy,and opened a brand-new era of philosophy.To retrospect and clear the course of Ontology’s naissance,development and perfection is very important for us to understand the respective status of Feuerbach’s philosophy and Marxism philosophy,and the successive relationship in scientific basis between the two philosophies as well.

Key words: Feuerbach, Marx, perceptual ontology, course
